ABSTRACT

Photographic composing machine for producing text layouts comprising a picture carrier having line elements, a sensitized photographic carrier having a light-sensitive coating interposed between the picture carrier and the photographic carrier which depicts a preselected line element in the plane of the lightsensitive coating whereby continuous relative motion of the depicted line element in relation to the sensitized photographic carrier draws lines in horizontal or perpendicular directions in one process with composing of the text.

HANS LIHDE PETER THIENEL lnvenm by arl 32w Attorney LINE-DRAWING APPARATUS IN PHOTOGRAPHIC COMPOSING MACHINES BACKGROUND OF THE INVENTION In the production of form setting, the problem of combined line and text setting occurs repeatedly in photographic composing machines.

Normally, this problem is resolved by producing the text and line sections of the copy on two different machines, after which it is assembled and copied together. It is also prior art for the lines to be composed of individual line elements of uniform or various length similar to the sequence of letters in the text, these being set in sequence through individual photographs. These two methods have the known disadvantages whereby the finite thickness of the sensitized coating prevents the text and line matter from lying on a uniform plane with consequent lack of a clearly defined image in the copy after the first release when recopying or after the second release, which is incidentally extremely time consuming, the connection points between the individual elements forming within the lines. The task, according to the invention, is based on remedying the foregoing defect.

SUMMARY OF THE INVENTION According to the invention, this task is resolved by providing, in addition to the picture carrier of the projector device and the sensitized coating carrier of a photographic composing machine, a picture carrier with line elements and a suitable projector device which depict a preselected line element of the picture carrier in the plane of the light sensitive coating of the photographic coating carrier, so that by means of a continuous relative movement of the depicted line element, in relation to the sensitized carrier, it is possible to draw lines in horizontal or vertical direction in one process, at the same time as the text is composed.

According to the invention, it is also possible, by means of the projector device, to project line elements for the type symbols which are provided on the type carriers onto the lightsensitive material of the photographic emulsion carrier so that when subjected to constant exposure in conjunction with continuous relative movement of the light-sensitive material in any predetermined direction relative to the projection image of the line element, it is possible to draw lines in one sequence together with composing of the text.

BRIEF DESCRIPTION OF THE DRAWINGS Embodiments of the invention are depicted in the drawing as follows:

FIG. 1 is a diagrammatic illustration of a photographic composing machine with an additional projector device for the line elements in accordance with the invention, and

FIG. 2 is a diagrammatic illustration of a device in accordance with the invention, employing the projector device which is provided for projecting the drawing.

DETAILED DESCRIPTION OF THE INVENTION For line drawing on a special picture carrier 1, with its own projector device 2, there are various horizontal and vertical line elements 3, of various thickness but uniform length. The selected horizontal line element is projected onto the surface of the sensitized photographic carrier 4 and, utilizing the translatory relative movement represented by arrow 5, the means for which is already known for moving the type forward, an image is drawn continuously on the sensitized photographic carrier 4, thereby forming a uniformly exposed strip,

the width of which is governed by the thickness of the projection image and which is then marked as a line after the film has been developed. With perpendicular lines, projection of the appropriate vertical element by means of vertical movement (arrow 7), which, of necessity, is also present, is operated on a continuously vertical pattern for the line spacing and accordingly forms a vertical or perpendicular line.

Projection of the line element lS focused through suitable optical aids as required by the special projector device 2, into the main beam path 8, in such a way that the optical axes of both systems either intersect in the image plane of the sensitized photographic carrier 4, or coincide in the last section of the optical beam path.

The movement of the sensitized photographic carrier 4 in the direction of the arrow 7 is effected by the motor 12 which can move the sensitized photographic carrier 4 up and down on the threaded spindle 13. In addition one of the bores in the sensitized photographic carrier, through which the spindle 13 engages, is provided with a corresponding thread, which is not further illustrated.

The translatory movement in the direction of the arrow 5 is effected by the motor 14 which can, with the threaded spindle 15, move the sensitized photographic carrier 4 to and fro in the horizontal direction. Also the spindle 15 engages through a recess of the sensitized photographic carrier 4 which is not shown and which is provided with a corresponding thread.

By this type of arrangement, it is possible to position both the text image and the line image in the same manner.

According to another version as per FIG. 2, the line elements 3 are also applied to the image carrier 9. They are projected via optical system 11, provided for projecting images 10, onto the light sensitive material of the sensitized photographic carrier 4.
